HARNESS FOR LQOMS OR THE LIKE.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed. November 4, 1915. Serial No. 59,562.

To 0. Z 207mm it may concern Be it known that I, EDGAR F. HATHAWAY, citizen of the United States, and resident of Boston, Massachusetts, have invented certain new and useful Improvements in Harness for Looms or the like, of which the following is a specification.

This invention relates to loom harness and is intended to provide simple, durable, and eflicient means of preventing the separation of the two legs Or branches of the looped cord by which the heddle eyes are suspended and to avoid the consequent shifting or displacement of the heddle'eye or thread eye from its proper position in the harness.

In commercial practice the suspension cords of the heddles are passed over the top of a suspension bar and looped through a small hole in the eye or warp-retaining member of the heddle, two branches of said cord being secured together by shellac or other adhessive just above the thread eye. This method of connecting or securing together the two branches of the cord is open to the objection that it is not absolutely reliable since the adhesive material may become softened by atmospheric changes or may crack, thus permitting the two strands or branches of the suspension loop to pull apart. Such pulling apart not only acts to interfere with the proper positioning of the heddle eye, but allows it to shift on the cord so that the tension on the two branches of the cord is unequal, thereby often producing breakage.

The tying together of the two members or branches of the suspension cord is not satisfactory because the presence of any knot or projection seriously interferes with the proper action of the loom harness, since such shoulder or projection tends to catch against adjacent warp threads carried by another set of heddles, besides tending to produce chafing of the warp threads of the heddles due to the relative reciprocation of the different sets of heddles. The present invention is intended to obviate all difiiculties by so fastening or securing the branches of the respective heddle members together that no obstruction or projection is formed, while at the same time the branches of the suspension cords are positively and reliably held together.

In the accompanying drawings I have illustrated the preferred embodiment of the present invention as applied to a loom harness, in which- Figure 1 is a front elevation showing a series of heddles fastened in accordance with this invention.

Fig. 2 is aside elevation showing two adjacent heddles slightly spread apart.

Fig. 3 is an enlarged detail view showing struction to receive the upper suspension cord 0 and the lower cords e which are passed around the respective bars after the usual practice and which are held in place by the anchoring cords a.

The heddle eyes 6 are provided with the elongated central opening 1; through which the warp threads are passed and are also formed with small perforations at their opposite ends through which the heddle cords c, 6, respectively, are passed in order to suitably suspend the eyes in operative position. In Fig. 2, two adjacent heddles are shown somewhat separated from their position of alinement in order that the looping of the suspension cords may be clearly understood.

The suspension cords c are passed over the upper bar and through the small suspension perforations 6 of the thread eye.

Instead of being glued together, however, I

employ a small clip d made of any suitable material such as thin sheet metal, which is passed around the two adjacent branches of a suspension cord just above the thread eye which it supports and which is clenched or clamped tightly around said branches of the cord, as best shown in F 3.

As it is important that any projection, shoulder, or ridge of any kind, against which any warp threads could catch, should be avoided, I prefer to use a form of fastening clip similar to that shown in Figs. 4: and 5, which is made U shaped with a single prong d on one side opposite to a corresponding notch or recess formed in the other side, which leaves on the other side two offset prongs (P so that when the clip is tightly set or clenched upon the cord the tongue or prong 03 will lie inside the recess formed between the pair of prongs (Z so that the strands of the cord may be encircled without producing any over-lapping of one branch oi the clip above the other. means of suitable liers or other setting device the clips may e ci'enched so tightly into the fiber of the cord that it lies slightly below the normal outside line of the two cords adjacent to the fastening, as clearly shown in Fig. 3.

It will, therefore, be seen that there is not the slightest obstruction or shoulder which can catch against the adjacent warp threads, while at the same time the lower looped'end of the cord has its two branches fastened to.

gether in a positive manner which precludes the possibilityof any slipping with relation to each other and makes it impossible for the heddle eye to change its position along its suspension cord.

I have shown the fastening clips-wrapped around and clenched upon the upper or sus pension cords of the harness eyes since o rdinarily the use of the clips on theupper cords is suflicient for practical purposes but it will be understood that I do not limit myself to that particular location or" the tion of the double strand so as to afford no projection beyond the outer surface of the adjacent portions of the double stranch the free endsof said clip being laterally offset when so embedded to pass beyond each other circumferentiall-y of the double strand thereby avoiding the overlapping of one end of the clip above the other, substantially as described.

In witness whereof, I have subscribed the above specification EDGAR F. HATHAWAY.
